The Old English of the Anglo-Saxon era developed into Middle English, which was spoken from the Norman Conquest to the late 15th century. A significant influence on the shaping of Middle English came from contact with the North Germanic languages spoken by the Scandinavians who conquered and colonised parts of Britain during the 8th and 9th centuries; this contact led to much lexical borrowing and grammatical simplification. Another important influence came from the conquering Normans, who spoke a Romancelangue d'oïl called Old Norman, which in Britain developed into Anglo-Norman. Many Norman and French loanwords entered the language in this period, especially in vocabulary related to the church, the court system and the government. The system of orthography that became established during the Middle English period is by and large still in use today – later changes in pronunciation, however, combined with the adoption of various foreign spellings, mean that the spelling of modern English words appears highly irregular.

Early Modern English – the language used by Shakespeare – is dated from around 1500. It incorporated many Renaissance-era loans from Latin and Ancient Greek, as well as borrowings from other European languages, including French, German and Dutch. Significant pronunciation changes in this period included the ongoing Great Vowel Shift, which affected the qualities of most long vowels. Modern English proper, similar in most respects to that spoken today, was in place by the late 17th century. The English language came to be exported to other parts of the world through British colonisation, and is now the dominant language in Britain and Ireland, the United States and Canada, Australia, New Zealand and many smaller former colonies, as well as being widely spoken in India, parts of Africa, and elsewhere. Partially due to United States influence, English gradually took on the status of a global lingua franca in the second half of 20th century. This is especially true in Europe, where English has largely taken over the former roles of French and (much earlier) Latin as a common language used to conduct business and diplomacy, share scientific and technological information, and otherwise communicate across national boundaries. English-speaking Christian missionaries spread English to many lands. It became a second language for most of the people groups where the missionaries went.

Old English consisted of a diverse group of dialects, reflecting the varied origins of the Anglo-Saxon kingdoms established in different parts of Britain. The Late West Saxon dialect eventually became dominant; however, a greater input to Middle English came from the Anglian dialects. Global geo-social variation among different English dialects and accents remains significant today. Scots, a form of English traditionally spoken in parts of Scotland and the north of Ireland, is sometimes treated as a separate language.

These dialects had most of the typical West Germanic features, including a significant amount of grammatical inflection. Vocabulary came largely from the core Germanic stock, although due to the Germanic peoples' extensive contacts with the Roman world, the settlers' languages already included a number of loanwords from Latin.[3] For instance, the predecessor of Modern English wine had been borrowed into early Germanic from the Latin vinum.

The dialects spoken by the Germanic settlers developed into a language that would come to be called Anglo-Saxon, or now more commonly Old English.[4] It displaced the indigenous Brittonic Celtic (and the Latin of the former Roman rulers) in most of the areas of Britain that later formed the Kingdom of England, while Celtic languages remained in most of Scotland, Wales and Cornwall, and many compound Celtic-Germanic placenames survive, hinting at early language mixing.[5] Old English continued to exhibit local variation, the remnants of which continue to be found in dialects of Modern English.[4] The four main dialects were Mercian, Northumbrian, Kentish and West Saxon; the last of these formed the basis for the literary standard of the later Old English period, although the dominant forms of Middle and Modern English would develop mainly from Mercian.

Old English was first written using a runic script called the futhorc, but this was replaced by a version of the Latin alphabet introduced by Irish missionaries in the 9th century. Most literary output was in either the Early West Saxon of Alfred the Great's time, or the Late West Saxon (regarded as the "classical" form of Old English) of the Winchester school inspired by Bishop Æthelwold of Winchester and followed by such writers as the prolific Ælfric of Eynsham ("the Grammarian"). The most famous surviving work from the Old English period is the epic poem Beowulf, composed by an unknown poet.

The introduction of Christianity from around the year 600 encouraged the addition of over 400 Latin loan words into Old English, such as the predecessors of the modern priest, paper, and school, and a smaller number of Greek loan words.[6] The speech of eastern and northern parts of England was also subject to strong Old Norse influence due to Scandinavian rule and settlement beginning in the 9th century (see below).

Most native English speakers today find Old English unintelligible, even though about half of the most commonly used words in Modern English have Old English roots.[7] The grammar of Old English was much more inflected than modern English, combined with freer word order, and was grammatically quite similar in some respects to modern German. The Old English period is considered to have evolved into the Middle English period some time after the Norman conquest of 1066, when the language came to be influenced significantly by the new ruling class's language, Old Norman.[8][9]

The Scandinavians, or Norsemen, spoke dialects of a North Germanic language known as Old Norse. The Anglo-Saxons and the Scandinavians thus spoke related languages from different branches (West and North) of the Germanic family; many of their lexical roots were the same or similar, although their grammatical systems were more divergent. Probably significant numbers of Norse speakers settled in the Danelaw during the period of Scandinavian control. Many place-names in those areas are of Scandinavian provenance (those ending in -by, for example); it is believed that the settlers often established new communities in places that had not previously been developed by the Anglo-Saxons. The extensive contact between Old English and Old Norse speakers, including the possibility of intermarriage that resulted from the acceptance of Christianity by the Danes in 878,[10] undoubtedly influenced the varieties of those languages spoken in the areas of contact. Some scholars even believe that Old English and Old Norse underwent a kind of fusion and that the resulting English language might be described as a mixed language or creole. During the rule of Cnut and other Danish kings in the first half of the 11th century, a kind of diglossia may have come about, with the West Saxon literary language existing alongside the Norse-influenced Midland dialect of English, which could have served as a koine or spoken lingua franca. When Danish rule ended, and particularly after the Norman Conquest, the status of the minority Norse language presumably declined relative to that of English, and its remaining speakers assimilated to English in a process involving language shift and language death. The widespread bilingualism that must have existed during the process possibly contributed to the rate of borrowings from Norse into English.[11]

Only about 100 or 150 Norse words, mainly connected with government and administration, are found in Old English writing. The borrowing of words of this type was stimulated by Scandinavian rule in the Danelaw and during the later reign of Cnut. However, most surviving Old English texts are based on the West Saxon standard that developed outside the Danelaw; it is not clear to what extent Norse influenced the forms of the language spoken in eastern and northern England at that time. Later texts from the Middle English era, now based on an eastern Midland rather than a Wessex standard, reflect the significant impact that Norse had on the language. In all, English borrowed about 2000 words from Old Norse, several hundred surviving in Modern English.[11]

Norse borrowings include many very common words, such as anger, bag, both, hit, law, leg, same, skill, sky, take, window, and even the pronoun they. Norse influence is also believed to have reinforced the adoption of the plural copular verb form are rather than alternative Old English forms like sind. It is also considered to have stimulated and accelerated the morphological simplification found in Middle English, such as the loss of grammatical gender and explicitly marked case (except in pronouns).[12] That is possibly confirmed by observations that simplification of the case endings occurred earliest in the north and latest in the southwest. The spread of phrasal verbs in English is another grammatical development to which Norse may have contributed (although here a possible Celtic influence is also noted).[11]

For centuries after the Conquest, the Norman kings and high-ranking nobles in England and to some extent elsewhere in the British Isles spoke Anglo-Norman, a variety of Old Norman, originating from a northern langue d'oïl dialect. Merchants and lower-ranked nobles were often bilingual in Anglo-Norman and English, whilst English continued to be the language of the common people. Middle English was influenced by both Anglo-Norman, and later Anglo-French (see characteristics of the Anglo-Norman language).

Until the 14th century, Anglo-Norman and then French were the language of the courts and government. Even after the decline of Norman, standard French retained the status of a formal or prestige language, and about 10,000 French (and Norman) loan words entered Middle English, particularly terms associated with government, church, law, the military, fashion, and food[13] (see English language word origins and List of English words of French origin). The strong influence of Old Norse on English (described in the previous section) also becomes apparent during this period. The impact of the native British Celtic languages that English continued to displace is generally held to be much smaller, although some attribute such analytic verb forms as the continuous aspect ("to be doing" or "to have been doing") to Celtic influence.[14][15] Some scholars have also put forward hypotheses that Middle English was a kind of creole language resulting from contact between Old English and either Old Norse or Anglo-Norman.

English literature began to reappear after 1200, when a changing political climate and the decline in Anglo-Norman made it more respectable. The Provisions of Oxford, released in 1258, was the first English government document to be published in the English language after the Norman Conquest. In 1362, Edward III became the first king to address Parliament in English. The Pleading in English Act 1362 made English the only language in which court proceedings could be held, though the official record remained in Latin.[16] By the end of the century, even the royal court had switched to English. Anglo-Norman remained in use in limited circles somewhat longer, but it had ceased to be a living language. Official documents began to be produced regularly in English during the 15th century. Geoffrey Chaucer, who lived in the late 14th century, is the most famous writer from the Middle English period, and The Canterbury Tales is his best-known work.

The English language changed enormously during the Middle English period, both in vocabulary and pronunciation, and in grammar. While Old English is a heavily inflected language (synthetic), the use of grammatical endings diminished in Middle English (analytic). Grammar distinctions were lost as many noun and adjective endings were levelled to -e. The older plural noun marker -en (retained in a few cases such as children and oxen) largely gave way to -s, and grammatical gender was discarded.

English underwent extensive sound changes during the 15th century, while its spelling conventions remained largely constant. Modern English is often dated from the Great Vowel Shift, which took place mainly during the 15th century. The language was further transformed by the spread of a standardised London-based dialect in government and administration and by the standardising effect of printing. As a result, the language acquired self-conscious terms such as "accent" and "dialect".[17] By the time of William Shakespeare (mid 16th - early 17th century),[18] the language had become clearly recognisable as Modern English. In 1604, the first English dictionary was published, the Table Alphabeticall.

Increased literacy and travel facilitated the adoption of many foreign words, especially borrowings from Latin and Greek from the time of the Renaissance. In the 17th century, Latin words were often used with their original inflections, but these eventually disappeared. As there are many words from different languages and English spelling is variable, the risk of mispronunciation is high, but remnants of the older forms remain in a few regional dialects, most notably in the West Country. During the period, loan words were borrowed from Italian, German, and Yiddish. British acceptance of and resistance to Americanisms began during this period.[19]

The first authoritative and full featured English dictionary, the Dictionary of the English Language, was published by Samuel Johnson in 1755. To a high degree, the dictionary standardised both English spelling and word usage. Meanwhile, grammar texts by Lowth, Murray, Priestly, and others attempted to prescribe standard usage even further.

Early Modern English and Late Modern English differ essentially in vocabulary. Late Modern English has many more words, arising from the Industrial Revolution and technology that created a need for new words, as well as international development of the language. The British Empire at its height covered one quarter of the Earth's surface, and the English language adopted foreign words from many countries. British English and North American English, the two major varieties of the language, are together spoken by 400 million people. Received Pronunciation of British English is considered the traditional standard. The total number of English speakers worldwide may exceed one billion.[20] The English language will almost certainly continue to evolve over time. With the development of computer use (chat rooms, domains, and apps etc. etc.), and the adoption of English as a worldwide lingua franca across cultures, customs, and traditions, we should not be surprised to see some further shortening of words, phrases, and/or sentences.

Over the last 1,200 years or so, English has undergone extensive changes in its vowel system but many fewer changes to its consonants.

In the Old English period, a number of umlaut processes affected vowels in complex ways, and unstressed vowels were gradually eroded, eventually leading to a loss of grammatical case and grammatical gender in the Early Middle English period. The most important umlaut process was *i-mutation (c. 500 CE), which led to pervasive alternations of all sorts, many of which survive in the modern language: e.g. in noun paradigms (foot vs. feet, mouse vs. mice, brother vs. brethren); in verb paradigms (sold vs. sell); nominal derivatives from adjectives ("strong" vs. "strength", broad vs. breadth, foul vs. filth) and from other nouns (fox vs. "vixen"); verbal derivatives ("food" vs. "to feed"); and comparative adjectives ("old" vs. "elder"). Consonants were more stable, although velar consonants were significantly modified by palatalization, which produced alternations such as speak vs. speech, drink vs. drench, wake vs. watch, bake vs. batch.

The Middle English period saw further vowel changes. Most significant was the Great Vowel Shift (c. 1500 CE), which transformed the pronunciation of all long vowels. This occurred after the spelling system was fixed, and accounts for the drastic differences in pronunciation between "short" mat, met, bit, cot vs. "long" mate, mete/meet, bite, coat. Other changes that left echoes in the modern language were homorganic lengthening before ld, mb, nd, which accounts for the long vowels in child, mind, climb, etc.; pre-cluster shortening, which resulted in the vowel alternations in child vs. children, keep vs. kept, meet vs. met; and trisyllabic laxing, which is responsible for alternations such as grateful vs. gratitude, divine vs. divinity, sole vs. solitary.

The following table shows the principal developments in the stressed vowels, from Old English through Modern English (C indicates any consonant):

The following chart shows the primary developments of English vowels in the last 600 years, in more detail, since Late Middle English of Chaucer's time. The Great Vowel Shift can be seen in the dramatic developments from c. 1400 to 1600.

Pronouns such as whom and him (contrasted with who and he), are a conflation of the old accusative and dative cases, as well as of the genitive case after prepositions (while her also includes the genitive case). This conflated form is called the oblique case or the object (objective) case, because it is used for objects of verbs (direct, indirect, or oblique) as well as for objects of prepositions. (See object pronoun.) The information formerly conveyed by distinct case forms is now mostly provided by prepositions and word order. In Old English as well as modern German and Icelandic as further examples, these cases had distinct forms.

Although some grammarians continue to use the traditional terms "accusative" and "dative", these are functions rather than morphological cases in Modern English. That is, the form whom may play accusative or dative roles (as well as instrumental or prepositional roles), but it is a single morphological form, contrasting with nominative who and genitive whose. Many grammarians use the labels "subjective", "objective", and "possessive" for nominative, oblique, and genitive pronouns.

Modern English nouns exhibit only one inflection of the reference form: the possessive case, which some linguists argue is not a case at all, but a clitic (see the entry for genitive case for more information).

(The origin of the modern forms is generally thought to have been a borrowing from Old Norse forms þæir, þæim, þæira. The two different roots co-existed for some time, although currently the only common remnant is the shortened form 'em. Cf. also the demonstrative pronouns.)

Lo, praise of the prowess of people-kings
of spear-armed Danes, in days long sped,
we have heard, and what honor the athelings won!
Oft Scyld the Scefing from squadroned foes,
from many a tribe, the mead-bench tore,
awing the earls. Since erst he lay
friendless, a foundling, fate repaid him:
for he waxed under welkin, in wealth he throve,
till before him the folk, both far and near,
who house by the whale-path, heard his mandate,
gave him gifts: a good king he!

Ohthere said to his lord, King Alfred, that he of all Norsemen lived north-most. He quoth that he lived in the land northward along the North Sea. He said though that the land was very long from there, but it is all wasteland, except that in a few places here and there Finns [i.e. Sami] encamp, hunting in winter and in summer fishing by the sea. He said that at some time he wanted to find out how long the land lay northward or whether any man lived north of the wasteland. Then he traveled north by the land. All the way he kept the waste land on his starboard and the wide sea on his port three days. Then he was as far north as whale hunters furthest travel. Then he traveled still north as far as he might sail in another three days. Then the land bowed east (or the sea into the land — he did not know which). But he knew that he waited there for west winds (and somewhat north), and sailed east by the land so as he might sail in four days. Then he had to wait for due-north winds, because the land bowed south (or the sea into the land — he did not know which). Then he sailed from there south by the land so as he might sail in five days. Then a large river lay there up into the land. Then they turned up into the river, because they dared not sail forth past the river for hostility, because the land was all settled on the other side of the river. He had not encountered earlier any settled land since he travelled from his own home, but all the way waste land was on his starboard (except fishers, fowlers and hunters, who were all Finns). And the wide sea was always on his port. The Bjarmians have cultivated their land very well, but they did not dare go in there. But the Terfinn’s land was all waste except where hunters encamped, or fishers or fowlers.[22]

Whan that Aprill with his shoures soote

Of Mans First Disobedience, and the Fruit
Of that Forbidden Tree, whose mortal tast
Brought Death into the World, and all our woe,
With loss of Eden, till one greater Man
Restore us, and regain the blissful Seat,
Sing Heav'nly Muse, that on the secret top
Of Oreb, or of Sinai, didst inspire
That Shepherd, who first taught the chosen Seed,
In the Beginning how the Heav'ns and Earth
Rose out of Chaos: Or if Sion Hill
Delight thee more, and Siloa's Brook that flow'd
Fast by the Oracle of God; I thence
Invoke thy aid to my adventrous Song,
That with no middle flight intends to soar
Above th' Aonian Mount, while it pursues
Things unattempted yet in Prose or Rhime.

The evening arrived: the boys took their places; the master in his cook's uniform stationed himself at the copper; his pauper assistants ranged themselves behind him; the gruel was served out, and a long grace was said over the short commons. The gruel disappeared, the boys whispered each other and winked at Oliver, while his next neighbours nudged him. Child as he was, he was desperate with hunger and reckless with misery. He rose from the table, and advancing, basin and spoon in hand, to the master, said, somewhat alarmed at his own temerity—

"Please, sir, I want some more."

The master was a fat, healthy man, but he turned very pale. He gazed in stupefied astonishment on the small rebel for some seconds, and then clung for support to the copper. The assistants were paralysed with wonder, and the boys with fear.

"What!" said the master at length, in a faint voice.

"Please, sir," replied Oliver, "I want some more."

The master aimed a blow at Oliver's head with the ladle, pinioned him in his arms, and shrieked aloud for the beadle.
